Abstract
Planning plays an important role in determining the degree of success realized by a new or small business. Essential elements to business success are identification of goals, followed by development of strategies to meet those goals. A business plan is an effective tool used by businesses to organize these goals and objectives into a coherent format. It can be defined as operating a company on paper. No matter the size or stage of development, companies use business plans to improve internal operations and to describe and market the business to potential outside financiers. A business plan should not only reflect the individuality of the new business but should also follow a standard format. This format is comprised of four major sections: introductory elements, business section, financial statements, and the appendix. This paper seeks to address that utilizing business planning as a tool will allow new or small businesses to achieve and even surpass their goals.

Abstract
Agile manufacturing is a new and revolutionary way of manufacturing and assembling products. It is the next logical step in the evolutionary chain of manufacturing technologies, following on the heels of its predecessors, craft production, mass production, and lean production. This paper explains what agile manufacturing is, and what needs to be done to successfully pave the way for its implementation. Successful implementation requires changes in five areas: government regulation, business cooperation, information technology, reengineering, and employee flexibility. The potential benefits of successfully implementing agile manufacturing are much too great for an organization to overlook, as are the potential consequences of failing to implement it. Though many organizations have made strides toward implementing agile manufacturing, there is much work that needs to be done. Corporations need the backing of strong infrastructure to make agile manufacturing successful. This will require cooperation between government and business.

Abstract
Purpose
This study aims to examine the effect of a combination of hybrid pin-fin patterns on a heat sink's performance using numerical techniques. Also, flow characteristics have been studied, such as secondary flow formation and flow-wall interaction.
Design/methodology/approach
In this study, the effect of hybrid arrangements of elliptical and hexagonal pin-fins with different distribution percentages on flow characteristics and performance evaluation criteria in laminar flow was investigated. Ansys-Fluent software solves the governing equations using the finite volume method. Also, the accuracy of obtained results was compared with the experimental results of other similar papers.
Findings
The results of this study highlighted that hybrid arrangements show higher overall performance than single pin-fin patterns. Among the hybrid arrangements, case 3 has the highest values of performance evaluation criteria, that is, 1.84 in Re = 900. The results revealed that, with the instantaneous change in the pattern from elliptic to hexagonal, the secondary flow increases in the cross-sectional area of the channels, and the maximum velocity in the cross-section of the channel increases. The important advantages of case 3 are its highest overall performance and a lower chip surface temperature of up to about 2% than other hybrid patterns.
Originality/value
Prior research has shown that in the single pin-fin pattern, the cooling power at the end of the heat sink decreases with increasing fluid temperature. Also, a review of previous studies showed that existing papers had not investigated hybrid pin-fin patterns by considering the effect of changing distribution percentages on overall performance, which is the aim of this paper.
